What 2D Tiler is

2D Tiler is a free web editor for building 2D game levels, tilesets, pixel assets, palettes, and export workflows. Its layered map editor includes paint, erase, fill, select, autotile, and object tools. Terrain workflows range from standard, diagonal, and sparse modes to 16-slot Wang autotiling and weighted terrain fill. For image editing, it offers pencil, eraser, bucket, line, rectangle, contour, selection, crop, move, and blur tools. Palette imports accept GIMP GPL, Adobe ASE, Aseprite, JASC PAL, Paint.NET TXT, and HEX lists. An AI asset workspace can create tilesets, sprites, backgrounds, icons, UI elements, and VFX through OpenAI, Google Gemini, xAI, and Together AI provider families. 2D Tiler runs locally in the browser, with projects kept in a browser-based workflow. Its native formats are .2dp projects, .2dm maps, and .2dt tilesets. Map workflows support Tiled, Godot 4, Unity, GameMaker, Defold, Phaser, tIDE, and Mappy formats. It is open source under the MIT License.
